You could jet through IR codes and see if you can find one to work, but why?
Recording from the FTA box onto your Tivo will be a manual process. You're going to have to set timers on the Coolsat reguardless.
I used to have my Coolsat 4000 connected to my Tivo. I did record stuff / timeshift. The recordings were titled whatever was on the channel that the Tivo thought it was watching.
Until Tivo gives us a means to build a custom guide, it'll always be a VERY manual process. This kills what makes a Tivo a Tivo. This is why I feel that the FTA PVRs (Pansat 5000 / 6000 etc) are a much better option for FTA use.
